Offna Hyper 7 nylon spur gear?

I'm running a Feigao 10L in my Hyper 7 with steel Mod-1 pinions. The spur gear is steel also which, I have read, is bad for reception and the two gears together make nice little metal particles in the chassis (yes, the mess is correct).
Where can I get a nylon spur gear for the Hyper 7? I see that Monster sells one, but I can't tell if it will work with the stock center diff and it is not in stock.

Can anyone help me out?

Thanks,

Chris

I couldn't find a nylon spur for my Hyper 7, which is why I ended up selling it and moving to the OFNA Ultra MBX. The center diff of the MBX is where that nylon spur was made to go.
You could buy new dogbones or have custom CVDs made and fit the MBX center diff into the Hyper 7 (I almost did), but I found it just as effective to move to a more cooperative platform.

I expect to finalize the Ultra MBX over this fall/winter.

I have a 9.5 that I've tried several different spurs on, Mod1 is the way to go. I obliterated a 66t 32p Kimbrough with my Lehner 2800xl, and the HPI 52t ones just barely stands up to it. Would a nylon one work better in my case? I actually wish I could use steel spurs, but that would screw over the pinion, so forget that. As it is, the way i have to mount a plastic spur on the diff is pretty ghetto anyway, did they ever make a composite or nylon or whatever one for the 9.5?

There is a way to tell if you can get a plastic spur gear for a diff - if the gear is attached directly to the diff cup via 4 screws, then you can't get a plastic gear. If the gear can be separated from the diff cup while the diff is still complete, then there is a plastic gear. An exception for this is the Kyosho buggies.

I used a kyosho gear on the lighting conversion i did.

Ofna uses a spider that holds the gear with 4 screws.
Mike normally has got the 51 tooth ofna gears.. (currently out of stock though)

The spur mounts directly to the one side of the diff case, but my ghetto way is a bit different. Would nylon be more durable than the HPI 52t plastic spur I trashed? My Lehner 2800xl seemed to do pretty good with 12/52 gearing on 12 cells in my 9.5, but I wish I could have a more durable gear, yet not lose the "give" of a non-metal spur.

Anyone know how to mod a clutch bell to fit a 1/8" Lehner shaft? I guess that'd be an idea.......:D

If you are good with CAD software then you can have custom made spur gears from Emachineshop.com, I tried it but it took too long for me to make the gear, (I not good with CAD software). Emachineshop can make gears out of any material, they also have Delrin.

I've done some CAD before, Solidworks and AutoCAD '05, but never quite got into it or even good. I would go with Solidworks if I was hard pressed to crank something out, but don't want to if I don't have to.

My main question would be this: what is the most durable NON-metal spur I could get a hold of?

that emachineshop is really simple..

Look at my avatar, i made it with 0 CAD experience
